Its possible that you looked at in while in DFCO, (fuel cut on decel). In that case, its possible that the tune is throwing 30's at it, trying to burn off the tiny bit of fuel thats present in DFCO. The reason for doing this is to eliminate backfire/popping from the unburnt gas (and trying to protect the CAT in doing so. )
